I think this guy missed the memo that Google bought Waze to put them out to pasture. They were the only real competition to Google Maps and were acquired to ensure Google Maps monopoly. Waze shipping features and winning in the marketplace would be a bad thing. I think a lot of his post stems from missing this.
Hard to align that perspective with his acknowledgement that Waze was allowed to operate independently, and the fact that Waze has been launching lots of new features for the last few years.
